What happens at 26 weeks pregnant?

What is developing at 26 weeks
The eyes begin to open for the first time, and the baby can blink. Brain activity in response to sight and sound can now be detected. The lungs carry on developing, and the baby practises drawing amniotic fluid in and out.
The size comparison above is a lolly snake, the party-bag monster, which measures 36 cm end to end. Every comparison on this site is a real object with a real measurement, checked against the published length. The same week is drawn in seven other sets below, from Australian animals to fast food, if this one means nothing to you.
26 weeks, in eight rulers
Every other pregnancy tool measures a baby in fruit. This one offers eight sets to choose from, and each object below carries its real measurement, checked against the 35.6 cm the NHS publishes for week 26. Pick whichever ruler you actually have a feel for. Why not fruit.

Questions about 26 weeks
- How many months is 26 weeks pregnant?
- 26 weeks is roughly 6 months. Months are an awkward unit in pregnancy because they do not divide evenly into weeks — a calendar month averages about 4.3 weeks, which is why 40 weeks works out a little over nine months rather than ten. Appointments and scans are always booked in weeks, so weeks are the figure worth carrying.
- How big is a baby at 26 weeks?
- The NHS publishes around 35.6 cm long, from head to heel for week 26. Rather than one fruit, that length is offered here against eight rulers, each object carrying its own measurement: a lolly snake, the party-bag monster (36 cm end to end), a crimson rosella (36 cm beak to tail), Woody (38 cm hat to boots), a senior shin pad (35 cm top to bottom), and four more. Published lengths are averages across many babies, not a measurement of any particular one, and a scan estimate that differs is a normal thing rather than a finding.
- What trimester is 26 weeks?
- Week 26 is in the second trimester, on the commonly published split of weeks 1–12, 13–26 and 27 onward. The boundaries are conventions for talking about pregnancy rather than biological switches — nothing changes overnight at week 13 or week 27.
Where these numbers come from
- NHS — Week-by-week guide to pregnancy — The published length of a baby at each week of pregnancy — measured head to bottom until week 20 and head to heel from week 20 — and what is developing at that stage.
- Pregnancy, Birth and Baby — Pregnancy week by week — The Australian Government health service’s week-by-week account of how a pregnancy is counted and what develops at each stage.
